To @ZZ whom it may concern: 1

Be it known that I, JOHN TAYLOR, of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Car-Trucks; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which-n Figure l is a side elevation of myimproved car-truck. Fig. 2 is a top plan view of the same. Fig. 3 lis a longitudinal vertical section through one of the pedestals, corner-castings, and connected parts, the axle-box being removed. Fig. 4 is a transverse sectional detail view of a corner-casting. Fig. 5 is a detail top view of one of these castings. Figs. 6 and 7 are detail views of the motor-sustaining-bars suspending devices. Figs. 8 and 9 are detail views of some of the frame-braces. Figs. l0, 11, 12, and 13 are detail views of the car-body-steadying devices.

This invention is an improved railway-car truck especially designed for electric roads; and its objects are to provide a compact, strong, easily-constructed truck in which the frame and supporting-springs of the car-body may be brought beneath the tops of wheels, thus bringing the body close to the ground; and it consists inthe novel construction of the frame as an entirety and in certain other novel details of construction and combinations of parts, as will be fully understood from the following description and claims.

Referring to the drawings by letters, A A designate the pedestals of the truck-frame, which are roughly of an inverted-U shape, and each consists of two vertical legs A A2, united at top by ahorizontal portion A2, which is longitudinally and horizontally bored or socketed, as at ce, above leg A2, this socket extending to about the inner edge of leg A', being closed at its inner end, and the top of the jaw is chambered above leg A', as at a. The

lower end of inner legs A2 are provided with short horizontal inwardly-opening sockets a2, and on the lower end of leg A is formed an upwardly-inclined socket a3, through the bottom of which is tapped an adjusting-bolt A4, These pedestals are hereinafter referred to.

arranged so that the legs A2 of the pedestals at the same side of the car adjoin, and they are united by horizontal beams B B, preferably tubular, the ends of which are respectively fitted into the sockets a and a2 of the adjoining pedestals. The beams are confined to the pedestals preferably by tie-rods B2, which pass through the pipes and perforations in bases of sockets o a2, and are secured by nuts, as shown, by which means the beams and pedestals are rigidly bound together. The chambers a above legs A allow the nuts on the upper rods B2 to be easily manipulated.

COareshortiiatbars,theinnerendsof which are iitted into rabbets A6 in the outer and inner faces of the pedestals, as' shown, so that said bars stand on edge parallel and horizontal and about in line with the upper beam B. The bars are connected to the pedestals by through-bolts c (which pass through the bars and pedestals above legs A thereof and through sleeves c', interposed between the walls of the pedestals in chamber a) and by tap-bolts c2, which pass through the walls of the pedestals and into the sides of pipes and prevent the latter turning in sockets a.

The outer extremities of the bars C C are united to corner-castings D. These castings have upstanding flanges D D', which receive the ends of the bars C C', and are secured thereto by through-bolts c4, passing through sleeves c5, interposed between the bars, and the upper ends of the anges are lipped over the edges of the bars, as at D2, so as to relieve the bolts of bearing strain. From the inner iiange of each of the corner-castings projects an inwardly-extending socket d, into which is fitted the extremities of an end bar b, preferably tubular, and b is a tie-rod ruiming through bar h and laterally through castings D, transfxing the ends of bars C C. in the casting, (between which bars a sleeve may be interposed on rod h,) and h2 b2 are nuts on the threaded ends of said rod, which, when tightened securely, binds the end beam to the castings. tion is made between the sides of the truckframe at the'ends. In some cases, instead of employing beams b the sockets d on castings D may be left off and the inner bars C G connected itogether at their outer ends by a flat By this construction a stiff connec- IOO bar C2; or a flat bar bent into a U shape will form the end bar and the two opposite inside bars C C at the end of truck. Both forms of end bars may be employed on the same truck, if desired, and where motors or brake mechanism is to be suspended from one end only the stiffer connection maybe used at that end.

On the bottom of each casting D which is roughly U-shaped in crosssection (see Fig. et) is a depension D3, to which the fender-hang ers are bolted, and at the inner extremity of this depension is formed an inwardly and downwardly inclined socket D1.

b" b4 are inclined braces, preferably tubular, inserted between sockets D4 of casting D and sockets as of the pedestals, so that weight on `the castings is transferred through said braces direct to the pedestals, and by means of bolts A4 the stiffness of braces can be regulated.

The axle-boxes, which move between the legs of the pedestals, as usual, are confined therein by bottom straps A7, bolted to the lower ends of the legs, as shown.

E E designate the body-springs, (which, asF

shown, are elliptical,) supported on castings D, being set longitudinally of the frame and resting on the bottom of the castings and partlybetween bars C C', the inner ends of the upper and lower leaves being connected by a countersunk rivet or bolt to permit it to play between the bars. The bottoms of the corner-castings are socketed, as at D, Figs. t and 5, to accommodate the bottom bands of the springs, which are secured thereto by clip-bolts E', as shown. The tops of springs may be clipped to bolster-plates E2, which in turn are bolted to the sills El of the car-body, as shown in Figs. l and 3.

In order to prevent undue lateral vibration of the body of the frame, as in rounding curves, guide-pins e5 may be employed. These may be arranged as shown in Figs. 10 to 13. In Figs.` 12 and 13 the pins e5 are bolted to the top sills of the ear and depend through castings e, bolted to the sides of the tiL1ckf1'anie, allowing free vertical movement of the body in relation to truck, but limiting its lateral movement thereon. In Figs. l0 and ll the guide-pins are bolted to the under surface of the sills and depend through openings ai in the top castings A above legs A and exterior to chamber ce. Then these guide-pins are employed, the springs E E need not be clipped to the carsills, but may rest against bearingplates E5, attached thereto, as indicated in Fig. l0. Then so arranged, the body can be quickly removed, and yet its steadiness while on the frame is insured.

F F are vertical braces connecting the upper and lower beams B and B near the pedestals. These braces are preferably made in two parts F F', each having its ends bent to partially embrace the beams, respectively, so put together their ends embrace that when the beams and constitute a connection equivalent to collars and straps. The two parts are united by bolts or rivets F2. These braces give rigidity to the frame and prevent diagonal twisting or working of the side frames of the truck.

G G are transverse stay bars or rods, connected to beams B', preferably at the points of connection of braces F thereto, and also preferably connected direct to said braces,- as, for instance, to a bracket f, inwardly projecting from the lower end of inner piece F,

Fig. 8, or to a stud or studsf", depending from the brace F, Fig. 9. The stays also serve as supports for the oil-pan or dust-guards of the motors. Then an internal brake is used,an inwardly-projecting hanger F2 may be cast on or rigidly secured to the upper ends of braces F, as indicated in Fig. 8.

II II are castings, which are secured centrally to and under beams B B by clips II Il and have recesses H2 112 in their ends, which receive the ends of motor-suspending bars I I, lying transversely of the truck-frame and vertically edgewise, being fastened to the castings by bolts Ils, which transfix the castings and ends of bars, as shown. The ends of bars fitting in the recesses of the castings will, when bound thereto, constitute a rigid and stiff support from which the electric motors may be suspended centrally of the car.

.I designates the plate, secured centrally to bars I, from which motors are hung. Then gearless motors are used, I prefer hanging them to crossbars K K, riveted or bolted to inside side bars C C', as shown in Fig. 2, in which case it is necessary to employ inside or between wheel brakes, which would be suspended from the brackets F2. (See Figs. 2 and 8.)

The brake-beams carrying the brake-shoes lie between the wheels and are suspended by links and controlled by springs, as indicated in the drawings. To the center of each beam is pivoted the end of the brakelever, the free extremity of which is connected by a rod to the brakechain at opposite ends of the cars. The brake-levers are connected to each other by a pitman, which is pivoted to each lever near the inner end thereof. By this arrangement when either chain is tightened the brakebeains are spread apart and forced against the wheels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is-
